District heating for Chinese teahouse, Hamburg, Germany

Monday, March 2, 2009

The exterior facade was delivered from China and Danfoss delivered a welded substation type FSD2550 H2 ECL 300 which transfers a capacity of 300 kW on 2 heating circuits and a domestic hot water system comprising a 500 liter storage volume.

Many things link the cities Hamburg and Shanghai to each other. Ever since September 2008 the reproduction of the legendary Huxing-Ting-Teahouse from the Yu-Garden in Shanghai counts as one of these things. With this gift to its sister city, Shanghai wishes to promote itself as the venue of the EXPO 2010. At the opening ceremony the governing mayor Ole von Beust ensured that you cannot tell the original and the copy apart. 115 tons Tai-Hu-Stones, 140,000 roof tiles and dozens of Chinese pine wood was shipped from Shanghai to Hamburg in 45 containers and assembled on a 3,400 m2 building ground in the Feldbrunnenstraße. Surrounded by an idyllic pond the building next to the Teahouse also houses a Snack-bar and the gourmet restaurant Lü Bolang.

Whereas the exterior facade originates from China for the most part, the building automation was delivered and installed by the firm Mackens & Sohn. The scope of delivery also includes a welded Danfoss substation type FSD2550 H2 ECL 300 which transfers a capacity of 300 kW on 2 heating circuits and a domestic hot water system comprising a 500 liter storage volume. The energy company Vattenfall delivers the district heating with a flow temperature of 136 °C and 25 bar.

Thanks to the customized substation with its optimal dimensioning, weather compensation and highquality automatic controls a maximum spread of 101 K is achieved. As a result, the return temperature is only 35 °C making the network and system operation very economic. Through the energy efficient operation mode the guests get to know the true promise of an extremely economic and environment-friendly heating solution, besides the culinary and cultural offers.
